Description

Technical Field

[0001] This utility model belongs to the field of safety monitoring and construction technology in hydropower engineering, and in particular relates to an easy-to-use vibrating wire surface joint gauge. Background Technology

[0002] In hydropower projects, changes in the expansion joints on the surface of structures have a significant impact on the overall safety of the project. Expansion joint gauges are suitable for installation within and on the surface of concrete or other material structures to measure the opening (deformation) of expansion joints or perimeter joints. For example, a vibrating wire expansion joint gauge transmits stress to the vibrating wire through front and rear supports, causing a change in the wire's vibration frequency. An electromagnetic coil excites the vibrating wire and measures its frequency. The frequency signal is transmitted via an observation cable to a reading device, allowing the measurement of the displacement of the structure. The working environment of the vibrating wire expansion joint gauge is particularly important.

[0003] Additionally, Chinese Patent Publication No. CN118758190A, entitled "A Bridge Crack Detection Device and its Detection Method," relates to the field of crack detection technology. It includes a detection platform fixedly mounted on a mobile vehicle. The detection platform comprises a detection arm and crack detection components mounted on the detection arm. The detection arm includes a horizontal arm extending along the width of the bridge to the outside of the bridge railing and a vertical arm extending downward along the height of the bridge to one side of the web of the bridge's box girder. However, existing methods for measuring surface cracks in buildings suffer from inconvenient installation and fixation, leading to inconvenience in use, and the inability to promptly view and provide early warnings of the detection results.

[0004] Therefore, it is essential to invent an easy-to-use vibrating wire surface gap gauge. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an easy-to-use vibrating wire surface crack gauge, which solves the problems of inconvenient installation and fixation for measuring surface cracks in existing building systems, resulting in inconvenience in use and the inability to view and provide timely warnings of the test results.

[0006] A user-friendly vibrating wire surface seam gauge includes a fixed angle plate, fixing bolts, a right side guard plate, a left side guard plate, a support rod, a corrugated belt, a displacement gauge, a detection rod, a left universal ball joint, an extension rod, a right universal ball joint, a sensor cylinder, a collar, a communication cable, and an integrated display unit. The fixed angle plate is an L-shaped angle steel plate. The fixing bolts are threaded from top to bottom to the upper left side of the fixed angle plate. The right side guard plate is screwed to the right side of the right-side fixed angle plate. The left side guard plate is screwed to the left side of the left-side fixed angle plate. The upper part of the support rod slides and engages with the lower part of the right side guard plate, and the lower end of the support rod is screwed to the upper part of the collar. The collar is slidably sleeved on the outside of the displacement gauge; the left universal ball screw is connected to the upper right side of the fixed angle plate on the left; one end of the extension rod is axially connected to the right side of the left universal ball, and the other end is inserted into the detection rod; the detection rod is inserted into the left side of the displacement gauge; the displacement gauge is axially connected to the left side of the right universal ball; the right universal ball screw is connected to the upper left side of the fixed angle plate on the right; the sensor cylinder is embedded inside the displacement gauge on the right side; one end of the communication cable is embedded in the right side of the displacement gauge, and the other end is electrically connected to the display all-in-one machine; the display all-in-one machine screw is connected to the upper part of the right protective plate.

[0007] Preferably, the corrugated strip is riveted at the intersection between the right side guard plate and the left side guard plate, and the corrugated strip is a corrugated rubber strip.

[0008] Preferably, the upper parts of the right side guard plate and the left side guard plate are respectively screwed with a carrying handle; the right side guard plate and the left side guard plate form a bridge shape.

[0009] Preferably, the displacement gauge also has a temperature sensor screwed inside.

[0010] Preferably, the all-in-one display unit has an alarm notification function.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This user-friendly vibrating wire surface joint gauge uses fixing bolts to secure the fixing angle plate to the surface of the building object to be inspected. During installation, the entire device is easily moved by holding the handle, increasing its convenience and flexibility, and making it suitable for various building applications. When the measured structure experiences joint displacement, it causes the displacement gauge, detection rod, and extension rod to extend and retract. This movement is transmitted through the left and right universal joints to the vibrating wire, resulting in a change in wire stress and thus altering the wire's vibration frequency. The frequency signal is transmitted via a communication cable to the integrated display unit, allowing for the measurement of the displacement of the measured structure. Simultaneously, the temperature value at the installation point can also be measured. Attached Figure Description
